Radioactive tracers are related to medicine, but they are used in several other fields. . It goes by several names, including radio-pharmaceuticals, radiotracer, and radioactive label. Radioactive tracers are chemical compounds that have radioactive atoms.
These atoms make it easier to be detected, as well as easier to be measured. These tracers are important in many imaging systems of the medical field, including PET scans. They are also used to research elements found in cells and biochemcial reactions.
Another purpose of these tracers is to track how fluids flow in gas. Examples of these tracers include carbon, oxygen, fluorine, iodine, and gallium.
A radioactive tracer is made up of some chemical compounds that are meant to trace the tissues and provide an image of them. Take note that this is not used to place radiation on the tissues of the body. This is safe so if you are told that you need to do this, you do not have anything to worry about.
Some people have already experienced some side effects because of this but these side effects are normal and will not last for a long time. Some of the usual side effects are bleeding from where the radioactive tracer has been injected. There are also some who may experience an allergic reaction to it.
To understand radioactive tracers it helps to first understand that all substances are made up of atoms and all atoms have a nucleus. The nuclei of some atoms will disintegrate and when they do, they give off energy in the form of particles or waves. This disintegration is called radiation or radioactivity.
The radiation can be detected and measured, for example, with a Geiger counter. There are also other kinds of radiation detection instruments that can measure the radioactivity being released. So radioactive tracers can be used to trace or follow how a substance moves through, for example, a plant or the human body.
